CPUs dedicate significant die area to smart control hardware like branch predictors, speculation, and out of order execution all necessary because general purpose software runs sequentially with unpredictable branching.GPUs restructure this tradeoff. AI workloads (matrix multiplies, dot products, etc.) are massively parallel the same operation applied to thousands of numbers simultaneously, with minimal branching in the hot path. That predictability means GPUs can afford simpler per-core control

The primary function that is lost from an underdeveloped prefrontal cortex is impulse control.We all feel impulses to do bad things, but when you have a more developed brain and higher IQ, you weigh the long-term consequences of taking that specific action, and if they are negative to you/others, you avoid the action.White Europeans evolved in the north where weather conditions were brutally-cold, which forced the growth of their prefrontal cortex, as long-term thinking was necessary for surviva
